At my Aikido dojo we are taught to apply kotegaeshi by placing one hand on uke for the grip, but using the other as a type of "hand blade" cutting towards uke through his hand.
I also train in Instinctive Response Training, where we practice with everything ranging from chokes, grappling, joint locks, weapons, etc. Anyway, we practice something that is clearly kotegaeshi, but there we use a way of doing it that Ive heard called a "butterfly grip" where instead you use both of your hands to grip uke's hand and apply the technique. I asked why, and I was told that this makes it harder for uke to turn his wrist out of it......what do you think?
